Question

in parallelogram ABCD angle A minus Angle B equals to 30 then find angle C​

Answer 1

Answer:

angleA+angleB =180 (adjacent angles)

angleA-angle B=30 (given)

= angleA+angleB +angleA -angleB =180+30

= 2angleA=210

angleA =105

angleA =angleC (oppoaite angle

Answer 2

In parallelogram ABCD angle A minus angle B equals to 30 degree. Then angle C is 105 degree.

• For a parallelogram ABCD, angle A + angle B = 180 degree.
• Given condition: angle A - angle B = 30 degree.
• Adding both, we get 2 * angle A = 210 degree. So, Angle A = 105 degree.
• Finally, angle A = angle C (angles at the opposite corners are same in a parallelogram)
• So, angle C= 105 degree.
